3. Which focus knobs can be used at each objective lens power?
A compound microscope has an objective lens with a focal length of 0.40 cm and an ocular (eyepiece) with a focal length of 4.25 cm. The separation between the lenses is 20 cm. (a) Find the total magnification. (b) What focal length of the objective should be used to double the total magnification, if the focal length of the eyepiece and its separation from the objective remain the same?
